My friends and I are having a dance marathon at my house for 12 hours( from 6:30 p.m. to 6:30 a.m.) I don't know that many fast songs that will keep us up for that long. The only songs I know are Gwen Stefani and P!nk songs. I'd hate to fall asleep standing up!

Just a few... Human - The Killers, Club can't handle me - Flo Rida, Ambitions - Joe McElderry or the original by Donkey boy,
DJ got us falling in love again - Usher, The Night is Young - Nelly Futardo, Dynamite - Taoi Cruz, If I had you - Adam Lambert
When Love takes over - David Guetta ft Kelly Rowland, One Love - David Guetta ft Estelle, Gettin' over you - David guetta ft Fergie
I got a Feeli'n' - Black Eyed Peas, Hey Ya - Outkast.
Lady Gaga also has quite a few 'dance ' songs, Just Poker Face etc
